Chinese Foreign Minister Wang Yi and Foreign Minister of El Salvador Carlos Castaneda signed a joint communique on Tuesday morning on the establishment of diplomatic relations between People's Republic of China and the Republic of El Salvador.
Taiwan President responded to the move by saying that cutting ties shows China's pressure on Taiwan, stressing that Taiwan would fight against China's "increasingly out of control" behaviour.
At the moment, there are only 17 states retaining official ties with Taiwan.
Official relations between central Chinese authorities and Taiwan stopped in 1949, when the Kuomintang government led by Chiang Kai-shek fled to Taipei after being defeated by the Chinese Communist Party, establishing the Republic of China on the island. Informal contacts resumed in 1980s.
Beijing does not recognize Taiwanese independence and claims the island is part of China. Taiwan similarly does not recognize the central government in Beijing.
